1. Delete user’s OLD mailbox from server since their name changed
2. Find local OLD OST on user’s PC
3. Want to restore OST file as PST to recover old emails into new mailbox
4. Download ost2.com software
5. Get "The file cannot be accessed because it has been configured
for use with a different mailbox" ERROR
How can I get the OST to become a PST so it can be read ?
